2. Save/restore CPU Interrupt state around sending IPI. It could avoid sending IPI be interrupted by CPU interrupt handler.
3. Add note for SetApicMode() API that must not be called from an interrupt handler or SMI handler.

Use the library functions for shift operations in BaseLib for a 64-bit integer where the code is shared for 32-bit and 64-bit.
Defining bitfields in structures with > 32 bits will cause these types of issues on IA32 builds. So the largest bitfield should be type UINT32 with a max size of :32.

1) No API change from old version.
2) Change MACRO:
#define MTRR_NUMBER_OF_VARIABLE_MTRR 32 // the semantics are changed from NUMBER to MAX_NUMBER.
#define FIRMWARE_VARIABLE_MTRR_NUMBER 6 // wrong and deprecated
#define MTRR_LIB_IA32_VARIABLE_MTRR_END 0x20F // wrong and deprecated
#define RESERVED_FIRMWARE_VARIABLE_MTRR_NUMBER 2 // add new one.
